	Left ventricular hypertrophy - Wikipedia, the free encyclopedia
		Left ventricular hypertrophy (LVH) is the abnormal thickening of the myocardium (muscle) of the left ventricle of the heart.
		Primary disease of the muscle of the heart that cause LVH are known as hypertrophic cardiomyopathies.
		Normal thickness of the left ventricular myocardium is from 0.6 to 1.1 cm (as measured at the very end of diastole.

	Atlas of Pathology (Site not responding. Last check: 2007-10-20)
		Hypertrophy of the left ventricle is defined as a wall thickness greater than 1.5 cm.
		When referring to an organ, hypertrophy means increased size of the organ and may be due to hypertrophy and/or hyperplasia (if the cells of the organ are capable of mitosis) of individual cells.
		Hypertrophy and hyperplasia are forms of adaptation and are thus reversible.

	Left Ventricular Hypertrophy
		LV hypertrophy is a powerful predictor of morbidity and mortality from myocardial infarction, stroke, and congestive heart failure [38, 39].
		LV hypertrophy is a common disorder, occurring in 16% of Whites, 21% of American Indians and 33 to 43% of African-Americans [40, 41].
		LV hypertrophy prevalence is particularly elevated in hypertensives, ranging from 22 to 60% [42], and varies by race [43].

	UpToDate Electrocardiographic diagnosis of left ventricular hypertrophy
		Left ventricular hypertrophy (LVH) refers to an increase in the size of myocardial fibers in the main cardiac pumping chamber.
		The major conditions associated with left ventricular volume overload are aortic or mitral valve regurgitation and dilated cardiomyopathy.
		Ventricular septal defects cause both right and left ventricular volume overload, while hypertrophic cardiomyopathy is an example of an inherited condition in which LVH (usually with asymmetric septal hypertrophy) occurs in the absence of any apparent hemodynamic pressure or volume overload.

	UpToDate Clinical implications and treatment of left ventricular hypertrophy in hypertension
		LVH diagnosed by echocardiography, which is much more sensitive than the ECG [14], also carries an increased risk for cardiac events (angina and myocardial infarction, heart failure, and serious ventricular arrhythmia) and cardiovascular deaths [7,10,12,15,16].
		After adjustment for other risk factors, LVH was associated with an increase in cardiovascular events (relative risk 2.08); for each 39 g/m2 increase in left ventricular mass there was a 40 percent increased risk of a major cardiovascular event (show figure 2).
		The prevalence of left ventricular hypertrophy was 22 percent and the risk factor adjusted hazard ratio for sudden death was 2.16 (p = 0.008).

	eMedicine - Hypertensive Heart Disease : Article by Kamran Riaz, MD
		LVH, defined as an increase in the mass of the left ventricle (LV), is caused by the response of myocytes to various stimuli accompanying elevated BP.
		Thus, the development of LVH is characterized by myocyte hypertrophy and by an imbalance between the myocytes and the interstitium of the myocardial skeletal structure.
		Left ventricular hypertrophy: The development of LVH is clearly related to an increase in the cardiovascular mortality rate.

		The aim of the sub-study is to determine the association of LVH, identified by echocardiography, with morbidity and mortality from cardiovascular events.
		The LVH sub-study has the objective to be community based, therefore echocardiography is conducted in a semi-mobile manner at various sites, which are conveniently located to recruited patients.

	Effect of left ventricular hypertrophy on the cardiac electrical field: The concept of specific potential of myocardium

		Changes in possible factors influencing QRS amplitude are not linear to increases in left ventricular mass, and the changes differ in different stages of experimental left ventricular hypertrophy.

		In the general population, left ventricular hypertrophy (LVH), either defined by echocardiographic or electrocardiogram (ECG) criteria, is strongly predictive of cardiovascular events, independent of conventional risk factors (1-3).
		In the general population, LVH causes electrical heterogeneity in the heart (6) and is associated with sudden cardiac death secondary to ventricular arrhythmias.
		This is consistent with previous studies suggesting the association between insulin resistance and LVH in both hypertensive subjects (18) and type 1 diabetic patients with nephropathy (4,5) and extends previous observations to normoalbuminuric subjects.

	Hemodynamics and other determinants in development of left ventricular hypertrophy. (Site not responding. Last check: 2007-10-20)
		Evidence is abundant supporting the premise that left ventricular hypertrophy in hypertension is related primarily to the hemodynamic factor of the increased left ventricular afterload associated with the disease.
		However, evidence is rapidly accumulating that additional, nonhemodynamic factors are associated not only with development of left ventricular hypertrophy but also with its regression that is related to antihypertensive therapy.
		Precisely how each factor is translated into the biochemical events associated with development of hypertrophy remains to be clarified, as do the explanatory mechanisms of why certain depressor agents produce regression of ventricular hypertrophy, whereas other agents with more salutary hemodynamic effects do not.

	Lars Erickson - Left Ventricular Hypertrophy
		Left ventricular hypertrophy (LVH) means that the muscle of the left pumping chamber of the heart (left ventricle) is thickened.
		The left ventricle's job is to pump blood to the body, and conditions that increase the work the left ventricle has to do can lead to thickening of the muscle.
		If there is any concern about whether a child with LVH on ECG actually has a heart problem, the usual next step would be to consider a consultation with a pediatric cardiac specialist and usually an ultrasound of the heart (echocardiogram).

		Etomoxir (2[6(4-chlorophenoxy)hexyl]oxirane-2-carboxylate), an irreversible carnitine palmitoyltransferase 1 inhibitor, reduces the expression of the myocardial foetal gene programme and the functional deterioration during heart adaption to a pressure-overload.
		Transformation of pressure values to ventricular wall stress data revealed an improved myocardial function which could partially account for the enhanced function of the whole left ventricle.
		The co-ordinated action of etomoxir on ventricular mass, geometry and myocardial phenotype enhanced thus the pressure generating capacity of hypertrophied pressure-overloaded left ventricles and delayed the deleterious dilative remodelling.

		The present studies were performed to investigate the mechanisms involved in left ventricular regression by moxonidine.
		Furthermore, in 60 µg-treated rats, ventricular DNA fragmentation was maximally increased at 1 and 2 weeks to 217% and 138% then decreased to 67% of untreated SHR, values not different from normotensive rats.
		This study demonstrates that moxonidine treatment results in regression of left ventricular hypertrophy through stimulating apoptosis (cell death), as evidenced by reduced DNA content and increased DNA fragmentation.

	Re: Left Ventricular Hypertrophy
		Left ventricular hypertrophy (LVH) is an enlargement of the left pumping chamber of the heart and may be due to several different things.
		Athletic hypertrophy is usually less than this thickness and will return to normal size with cessation of the activity.
		HOCM may be diagnosed in the absence of other causes of LVH and with the presence of a family history.
